Browsing: Evolution
Evolution is the fundamental biological process through which species change over generations, driven by mechanisms such as natural selection, mutation, genetic drift, and gene flow. It explains the diversity of life on Earth and how organisms adapt to their environments over time. Through the study of fossils, genetics, and comparative anatomy, scientists trace the origins and relationships of species, from microbes to humans. Evolutionary biology connects disciplines like genetics, ecology, and paleontology to reveal how complex traits arise, how new species form, and how life has persisted through billions of years of environmental change and planetary transformation.
